Subject: [Bug target/30047] Corrupt return value in specific context
Date: Sun, 08 Jun 2008 20:02:00 -0000	[thread overview]
Message-ID: <20080608200146.24984.qmail@sourceware.org> (raw)
In-Reply-To: <bug-30047-13405@http.gcc.gnu.org/bugzilla/>



------- Comment #2 from gcc at david dot osborn dot name  2008-06-08 20:01 -------
Created an attachment (id=15738)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15738&action=view)
compiler output

This shows bad code being generated.  The return value (12345) gets pushed into
eax on line 77, and then is subsequently overwritten for a call to
__Unwind_SjLj_Unregister.  Line 85 was added by me to show how to recover the
return value.
